are these unlocked chips? nvm they aren't ....**** one of these chips costs as much as the 980X far out

what's the system used for?

Thanks...and not likely unlocked...they're weird.
those X5650s are recognized as B0 Steppings while E-LEET shows B1. I was not able to adjust the uncore frequency even there's an option in BIOS. This system will be used most as server prototype and video encoding, while gaming is not likely as I still have my Q9650 @ 4.275Ghz running like a charm. CPU1's X5650 was crap, need 1.31vCore and 1.425vTT to be prime stable @ 20x200 (4000 uncore).
For those CPUs and the MB they cost around 2925AUD. (that's 19890HKD, bought from Hong Kong)
